Abstract

A luminance enhancement film (125) having a built-in light diffusing structure. The support substrate (132) incorporates a dispersion of particles (140) for light diffusion. In accordance with the present invention, a separate particle layer is not required in addition to the support substrate layer. The particles are integrated in the unitary support substrate layer. In one aspect of the present invention, the particles are dispersed near at least one of the planar surfaces of the support substrate (i.e., the light input surface light output surface or both of the support substrate. All the particles may be embedded below the surface of the support substrate, or some of the particles may protrude above the surface of the support substrate. In one embodiment of the present invention, the support substrate contains particles that are dispersed only close to its surface and form protrusions at the surface (i.e., the particle dispersed surface is not smooth).
